Title: Method and system for combining symmetric DSL signals and voice signals
Inventor: CHAPLIK NAOM
IPC: H04M11/06
Filed: 2000-10-19
Granted: 2002-07-01
Abstract: This invention provides a simplified communication system that transmits voice and SDSL signals between customer premise equipment (""CPE"") on a single twisted-pair line. The system preferably includes at least one combiner for combining voice and SDSL signals into a combined voice/SDSL signal that can be transmitted to the CPE on a single twisted pair of wires, preferably a pair of wires currently being used to transmit the voice signal to the CPE. One combiner is ideally located at a common wiring closet of the building where the CPE is located. The combiner is ideally coupled to the existing pair of wires for the voice signal. This eliminates the need to add another set of wires between the common wiring closet and the CPE for the SDSL signal. A second combiner, normally located at or near the CPE, separates the combined voice/SDSL signal into the separate voice and SDSL signals for processing by the CPE. The second and first combiners normally also combine and separate, respectively, the voice and SDSL signals transmitted from the CPE.

Title: A contact type micro piezoresistive shear-stress sensor
Inventor: FANG YAN-KUEN
IPC: B81B3/00
Filed: 2000-11-16
Granted: 2001-09-21
Abstract: In this invention, a contact type micro piezoresistive shear-stress sensor is fabricated by the micro-electro-mechanical (MEMS) technology, and its main sensing part is a 2-X shaped with a flange structure, for measuring the shear stress distribution between socket of above-knee (AK) prostheses and the soft tissue of amputee's stump. Comparing with a conventional shear stress sensor, this invention owns the following characteristics: piezoresistivity of the monolithic silicon will be utilized to convert shear deformation of the sensor into electrical signal and a micro sensor which can measure the shear force vector acting the sensing flange. The preparation processes of this invention are described as followings: A 3000x3000x300 μm<SP>3</SP> diaphragm is prepared by anisotropic wet etching of bulk silicon in KOH solution and a square flange with 1100x1100x3 μm<SP>3</SP> above the sensing diaphragm is formed through surface micromachining of deposited SiO2 thin film. With ion implantation, two X-shapes were placed at the closely middle points between mid-edge points and center of the diaphragm where less sensitivity to normal pressure and higher sensitivity to shear stress. The sensitivity of 3.6 uv/mA-Kpa for a 70 Kpa full scale (FS) shear-stress range with shear-stress hysteresis errors of less than 8.9% FS has been measured in the developed shear-stress sensor.

Title: Substrate structure of semiconductor packaging article
Inventor: HUANG CHUNG-PING
IPC: H01L21/56
Filed: 2001-02-20
Granted: 2002-01-21
Abstract: This invention provides a substrate structure of semiconductor packaging article. A stripped copper layer is placed on a substrate coated with core layer of solder mask. The edges of the two longer sides of the copper layer are partly covered with the solder mask so that the copper layer without the coverage of solder mask can be gold plated for the use as encapsulation runner. The width of the edges of the two longer sides of the copper layer partly covered by solder mask is between 0.1 mm and 1.0 mm and the preferred value is 0.5 mm. This allows the shrinking area of the solder mask covering the edges of the two longer sides of the copper layer to extend away from the runner and thus provides sufficient cramping area during in-mold encapsulation. Therefore, after the encapsulation, residual resin on the runner can be easily removed without damaging the structure of the packaging article and flash phenomenon can be effectively prevented due to sufficient cramping.

Title: Method and computer program product for designing combinatorial arrays
Inventor: AGRAFIOTIS DIMITRIS K
IPC: G16C20/62
Filed: 2001-03-01
Granted: 2003-03-11
Abstract: A greedy method for designing combinatorial arrays. An array of reagents are initially selected from a list of candidate reagents in a combinatorial library. The reagents in the array that maximize a design objective are determined in an iterative manner, by examining each variation site in the combinatorial library in a strictly alternating sequence. During each step, each candidate reagent at a given variation site is evaluated by constructing and evaluating the sub-array resulting from the systematic combination of that reagent with the selected reagents at all the other variation sites in the library. The candidate reagents at that variation site are ranked according to the fitness of their respective sub-arrays, and the reagents with the highest fitness are selected. The process is repeated for each variation site in the combinatorial library, until the fitness of the full combinatorial array can no longer be improved.

Title: Programmable electric capacitance micro-pump system
Inventor: YANG SHENG-JENN
IPC: B81B3/00
Filed: 2001-05-23
Granted: 2004-01-01
Abstract: A programmable electric capacitance micro-pump system is different from a conventional micro-pump system. The invented micro-pump does not require a check valve or a nozzle as needed in a conventional micro-pump, and has a different fluid driving method from that of a conventional micro-pump. Meanwhile, the invented micro-pump is capable of programmable electrical control of the direction and rate of fluid flow, and has a simplified chamber structure. Thus, the present invention has advantages including simple production process, high reliability, high yield, low cost, and suitable for mass production, etc. A conventional micro-pump system generally comprises two major parts: an actuating chamber with a reciprocative and vibrational membrane chamber for driving a fluid flow, and a check valve chamber for providing a one directional fluid flow. The two parts generally are produced separately and glued together into an integral micro-pump. Thus, the production of a conventional micro-pump is time consuming and has a poor yield and reliability. The invented capacitive micro-pump does not require a valve and a diffusion opening/nozzle structure, and requires only a longitudinal, flat and rectangular micro fluid flow chamber where the top and bottom faces of the chamber are covered with an elastic membrane plated with a plurality of strip-like (grid-like) metal electrodes. A capacitive electrostatic suction force generated between the grid-like electrodes and the bottom electrode of the chamber and the return force of the elastic membrane are used. An actuating voltage with a suitable phase difference is applied on each grid-like electrode to drive the elastic membrane in order to generate a plurality of unidirectional traveling waves so that the elastic membrane drives a fluid flow in a pulsation manner, thereby enabling a smooth and efficient operation of the micro-pump. The invented programmable electrostatic micro-pump system provides a longitudinal, flat and rectangular micro-chamber where each grid-like metal electrode thereon is adequately connected. Moreover, an external programmed voltage is applied to drive the elastic membrane to generate a transversal advancing wave or pressure field, where the direction of the fluid flow can be pre-selected.
